A delightful day is dawning in the mountains, with mostly clear skies, very light winds, and temperatures in the mid teens. Excellent powder remains on the shady slopes, with the crusts on the sunny slopes varying from place to place depending on how much sun the slope has received.
There was a skier triggered slide yesterday on Gobblers Knob, on a northwest facing slope at 9800. It was about 100 wide, a foot deep, and long running. It occurred mid afternoon, shortly after the sun had intensified, and heating was likely a factor. Today, with mostly sunny skies and warming temperatures in the forecast, the danger of wet sluffs and slabs will increase as the snow heats up. This will first occur on east and southeast facing slopes, then continue its way around the compass all the way to northwest. With the sun much higher in the sky, even shady slopes will be affected.
There were also several
reports of slope cuts releasing sluffs and shallow soft slabs in the snow from
the last storm. These were mostly manageable,
but some were large enough to take you for a ride. And finally, it may still be possible to
trigger a deeper slab avalanche in isolated places. Explosive control work in the Cottonwoods and
Bottom Line (
The avalanche danger is MODERATE on slopes steeper than about 35 degrees, with both loose sluff and slab avalanches possible. The danger of wet sluffs and slabs will increase significantly throughout the day. On slopes less steep than about 35 degrees, the avalanche danger is generally LOW.
High pressure will bring dry and warm weather to the Wasatch mountains today. Skies will be mostly sunny, with highs reaching into the mid 20s at 10,000 and the mid 30s at 8,000. The southwesterly winds will be light, less than 10 mph. After a clear, calm night, the next Pacific storm system will start to affect northern
